Signaling in Plant-Microbe Interactions

Plants are attacked by different kinds of pathogens; therefore plants have evolved defense mechanism to combat the pathogen attack and diseases. Many microbial signature molecules, which are known as microbe associated or pathogen associated molecular patterns (MAMPs/PAMPs) are recognized by a plant’s primary layer of immune response, known as PAMP-triggered immunity (PTI). In the co-evolution of plant-microbe interactions, successful pathogens have acquired the ability to deliver effectors proteins directly inside plant cell to suppress PTI, allowing pathogen growth and disease. As a counter measure, plants have developed a second layer of defense system, by acquiring the ability to recognize these…
